LOCATION: The site of the proposed crossing and potential temporary discharge of fill material into 165 linear feet of the Harpeth River is located near the intersection of Lewisburg Avenue and Carnton Lane, Franklin, Williamson County, Tennessee. Latitude: 35.913621, Longitude: -86.863332.

DESCRIPTION: A gas line will be installed underneath the bed of the Harpeth River using Horizontal Directional Drilling (HDD) methods. In the event of the inadvertent loss of drilling fluid (a "frac-out"), a contingency plan will be implemented to contain the spill. It involves the temporary discharge of fill material into 165 feet of the Harpeth River. The site has been disturbed previously by roads and residential development and previously installed pipelines are in the vicinity as well.

Plans of the proposed work and a location map are attached to this notice. If you wish to view additional plans, please contact this office or visit our website at:,

PURPOSE AND NEED: The applicant has stated that the purpose of the proposed project is to replac an existing gas distribution line that served a similar function. The proposed project is needed to maintain the availability of natural gas to Franklin, Tennessee residents.

AVOIDANCE AND MINIMIZATION OF IMPACTS TO WATERS OF THE U.S.: The applicant will be using Horizontal Directional Drilling technology, no direct effects to the Harpeth River are expected except in the event of a frac-out. In the instance of a frac-out, hand-placed containment such as silt curtains or turbidity barriers will be placed, and a vac-truck employed if necessary. All fill contingency measures will be removed when no longer needed.

PUBLIC INTEREST REVIEW/CUMULATIVE EFFECTS: The decision whether to issue a permit will be based on an evaluation of the probable impact including cumulative impacts of the proposed activity on the public interest. That decision will reflect the national concern for both protection and utilization of important resources. The benefit which reasonably may be expected to accrue from the proposal must be balanced against its reasonably foreseeable detriments. All factors which may be relevant to the proposal will be considered including the cumulative effects thereof; among those are conservation, economics, aesthetics, general environmental concerns, wetlands, historic properties, fish and wildlife values, flood hazards, floodplain values, land use, navigation, shoreline erosion and accretion, recreation, water supply and conservation, water quality, energy  needs, safety, food and fiber production, mineral needs, considerations of property ownership, and, in general, the needs and welfare of the people. In addition, the evaluation of the impact of the  activity on the public interest will include application of the guidelines promulgated by the Administrator, Environmental Protection Agency, under authority of Section 404(b)(1) of the CWA(40 CFR Part 230).

SOLICITATION OF COMMENTS: The United States Army Corps of Engineers (USACE) is soliciting comments from the public; federal, state, and local agencies and officials; Indian Tribes; and other interested parties in order to consider and evaluate the impacts of this proposed activity. Any comments received will be considered by the USACE to determine whether to issue, modify, condition, or deny a permit for this proposal. To make this decision, comments are used to assess impacts on endangered species, historical properties, water quality, and general environmental effects, and the other public interest factors listed above. Comments are used in the preparation of an Environmental Assessment (EA) and/or an Environmental Impact Statement pursuant to NEPA. Comments are also used to determine the need for a public hearing and determine the overall public interest of the proposed activity.  An EA will be prepared by this office prior to a final  decision concerning issuance or denial of the requested DA Permit.
